You are to demonstrate that you understand slope. you are to draw two graphs of lines. one line needs to have a slope of 2/3 and the second line needs to have a slope of -4.

In mathematics, the slope is used to describe the steepness and direction of straight lines.

Then knowing the slope and one point in the line , you can write the equation of this line.

If m is the slope of the line

The equation of this line is Y = mX + d  

d indicates the intersection point of the line with the y-axis, where X=0 (0,d)

To draw a line in the coordinate system (x,y), we have to calculate two points and then draw a line that passes through those two points. The first point is the intersection of the line with the vertical y-axis. We already know that it is (0,d) and another point can be the intersection of the line with the horizontal x-axis. To find it we have to substitute in the equation making Y = 0.

First equation : Y = 2/3X + b  where b is any value where the line will cut to the y-axis

intersection point of this line with the vertical y-axis => (0,b)

intersection point of this line with the horizontal x-axis, making Y=0

2X/3 + b = 0

X = -3b/2

intersection point of the line with the horizontal x-axis => (-3b/2,0)

Second equation : Y = -4X + c where c is any value where this line will cut to the y-axis

intersection point of the line with the vertical y-axis => (0,c)

intersection point of this line with the horizontal x-axis, making Y=0  

-4X + c = 0

X = -c/-4 = c/4

intersection point of the line with the horizontal x-axis => (c/4,0)



the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
